Abstract

This research paper introduces a compact multiple-input, multiple-output (MIMO) ultra-wideband (UWB) antenna design featuring an eye-shaped slot configuration. The proposed antenna structure comprises two eye-shaped slots positioned on a ground plane, with the strategic insertion of a T-shaped stub to enhance their isolation. The antenna exhibits an impressive impedance bandwidth spanning 3.5 GHz (4.83 to 8.35 GHz) while maintaining a compact footprint of 18.36 mm². Throughout the operational bandwidth, the mutual coupling between the two slots remains consistently below 20 dB. The research encompasses comprehensive modeling, manufacturing, and rigorous performance assessment through simulation and experimentation. The results validate the antenna's capabilities, demonstrating favorable radiation patterns, a low envelope correlation coefficient (ECC), and a substantial diversity gain. These attributes position the antenna as a promising candidate for integration into portable UWB devices, particularly as a sensor component, thus expanding its utility in wireless communication and sensing applications.
